90 cuscus. 



(skull of N". 88); one has iu each upper jaw two small 

 premolars instead of one, viz: N^. 104 (skull of N". 36); 

 these spurious teeth are very small and sharply pointed. 

 A skull, NO. 139 (of N». 80) has a single small right low- 

 er premolar and two small left lower premolars; two have 

 two small premolars in each lower jaw, viz: N°. Ill 

 (skull of N". 43) and No. 148 (a not fullgrown from Kein- 

 wardt's voyage) ; two have two small right lower premo- 

 lars, viz: N^ 109 (skull of N». 41) and N". 121 (skull 

 of N°. 57); two have two small left lower premolars, viz: 

 N°. 126 (skull of NO. 66) and N". 140 (skull of No. 81); 

 two have four small right lower premolars, viz: N**. 147 

 (skull of N'^. 88) and N^. 149 (a halfgrown from Banda) ; 

 one has four small left lower premolars , viz : 119 (skull 

 of No. 53) ; finally one has five small right and four small 

 left lower premolars, viz: N". 104 (skull of No. 36): I 

 remember that this skull has in each upper jaw two small 

 premolars instead of one small premolar (see above). 



Among forty skulls belonging to mounted specimens of 

 Cuscus maculatus there are fifteen in an abnormal con- 

 dition as to the dentition: one, viz: N". 55 (skull of N". 5) 

 has in each upper jaw two incisors instead of three, and 

 in the left upper jaw only the hindmost premolar and no 

 trace of the two others ; two , viz : No. 84 (skull of W, 39) 

 and NO. 86 (skull of N". 43) have in each upper jaw a 

 small and pointed premolar placed between the two other 

 premolars , and in each lower jaw three small premolars , 

 instead of two : these spurious premolars are placed very 

 close to the hindmost lower premolars; one, viz: N". 74 

 (skull of No. 26) has in the right upper jaw a small pre- 

 molar placed between the two others ; three , viz : N". 76 

 (skull of N». 29) , NO. 80 (skull of N". 34) and No. 82 

 (skull of NO. 37) have in each upper jaw a small premo- 

 lar placed between the two other premolars like in Cus- 

 cus orientalis; two, viz: N". 58 (skull of No. 8) and N". 91 

 (skull of N". 48) have only one small premolar in each 

 lower jaw; two, viz: No. 65 (skull of N". 16) and No. 89
